To evaluate whether methyl isobutyl ketone (MIBK) affects reproductive performance, a two-generation reproduction study was conducted. MIBK was administered to 30 Sprague-Dawley rats/sex/group via whole-body inhalation at concentrations of 0, 500, 10

Sequential morphological changes occurring after brief carcinogen exposures of heterotopic tracheal transplants in rats were semiquantitatively studied. Tracheas were exposed to 7,12-dimethylbenz(a)anthracene for 1, 2, or 4 weeks, during which time m

The cocarcinogenic effect of chrysotile asbestos was investigated in heterotopic tracheal transplants of F344 rats. Tracheal transplants were first exposed to graded doses of dimethylbenz[a]anthracene (DMBA) contained in intraluminal pellets. The dos

Experiments were conducted to determine whether two-stage carcinogenesis could be observed in rat tracheal epithelium using 7,12-dimethylbenz(a)anthracene (DMBA) as initiator and 12-O-tetradecanoylphorbol-13-acetate (TPA) as promoter. Heterotopic tra

The purpose of the studies was to examine the acute, chronic, and neoplastic effects of asbestos on mucosa of conducting airways. Heterotopic tracheal grafts were used as the experimental model. In the system employed, the test substance was introduc
